People are really good at supporting ideas that harm themselves.

Just see any country and any election ever. Hopefully they don't win but you will always have a significant minority wanting to create a shithole for everyone themselves included.

I've met people like that and they're all insufferable edge lords. Trump is a contrarian and to them contrary is correct.

So gut instinct: he’s probably a misogynist first and black and gay come after that. It may not be correct but holy hell as a lesbian it describes a lot of the gay male conservatives I’ve met.

The more nuanced potential is that people don’t like being put into boxes or perfectly matching stereotypes. Additionally many people can’t read between lines even when it’s obvious. Trump went very hard against immigrants and Black Lives Matter protesters, and he has white supremacists supporting him and a history of anti black prejudices, but he’s never said that he hates black people. Similarly he’s ranted and raved about trans people, and he allies with people who hate gay people, but his words are not explicitly against cis gay people. So if he wanted to be willfully ignorant to declare himself as the special good one who won’t be boxed in by your preconceived notions of what he should be, all he has to do is not read the obvious messages between the lines and hope they go away.

If I had to guess it's money.
